1Gấu ú May mắn. Question: What is the length of the side of a square with an area of 9 square centimeters?
Answer: Since the area of the square is equal to the square of the side length, the side length is the root number 9, which is 3 cm.
Analysis: This question examines the area formula of a squareTổ Ong Thịnh Vượng. The edge length is calculated by the formula.
2. Problem: If we know that the two roots of the unary quadratic equation ax²+bx+c=0 are x₁ and x₂, then the discriminant formula Δ=_______.
Answer: Discriminant Δ = b²-4ac. If Δ>0, the equation has two unequal real roots; If Δ=0, the equation has two equal real roots; If Δ<0, the equation has no real roots. Analysis: This question examines the discriminant formulas of one-dimensional quadratic equations and their applications.
